Effects of Sunlight on Fluorescence of Diamonds

Fluorescence can be used to save up costs of up to 20% on your center rock when you’re going diamond shopping for the wedding. Explore the complete guide on what fluorescence of diamonds are as well as the 5 types to ensure you’re buying a great diamond will guide you in the post below. Get started!

How do I Understand Diamond Fluorescence?

Fluorescence occurs in many gemstones. The property of fluorescence is one of the many optical illusions you can see in natural gemstones. When a gemstone absorbs the UV light, it glows in another color. This optical quality of diamonds is referred to as diamond fluorescence.

In the diamond report by GIA approved gemologists, you will notice fluorescence is the power of the diamond to react when the UV rays fall on it. GIA claims that over 95% of diamonds radiate fluorescence in a blue color due to the inclusions of boron within it. Out of this, up to 30% diamonds show moderate fluorescence and 10% show fluorescence that changes the diamond under normal light.

Fluorescence of diamonds is observed in diamonds devoid of any color. For example, colorless diamonds give a blue fluorescence unlike a yellow precious rock. Fluorescence is the same reason why yellow diamonds can appear regal, costly and white!

What are the Effects of Sunlight on Fluorescence of Diamonds?

What are the five types of fluorescence of diamonds? Learn everything about fluorescent glowing diamonds in the next five minutes!

1. Fluorescence

What are No Fluorescent Diamonds?

Diamonds that do not emit any fluorescence are non-fluorescent diamonds. These loose diamonds look transparent and colorless under UV light or any other light than the natural light. If you’re into fluorescence, ‘none’ is a trait you must avoid when shopping for fluorescent diamonds.

2. Faint Fluorescence

What are Faint Fluorescent Diamonds?

The first category of fluorescence of diamonds is ‘Faint’. When you pick a diamond with faint fluorescence, it does not affect the color or appearance of the rock. Moreover, faint fluorescence cuts the total price of the diamonds. So, if you choose a grade G diamond with faint fluorescence, you will save hundreds of dollars besides getting a rock that looks colorless and pricey at the same time!

3. Medium Fluorescence

What are Medium Fluorescent Diamonds?

Another class of fluorescent diamonds that do not emit haziness when you look at the precious rock, medium fluorescence is best for diamonds with color H grade. As the fluorescence is in a blue glow, yellow diamonds with fluorescence will neutralize the blue to become white. Thus, you can select a medium fluorescence yellow diamond and make it look triple the price!

Although, when under the sun, the fluorescence will show clearly, so watch out!

4. Strong Fluorescence

What are Strong Fluorescent Diamonds?

One of the heaviest florescences of diamonds is visible with Strong fluorescence diamonds. They are hazy and not particularly recommended as it lowers the brilliance of your diamond. Moreover, if you select diamonds with colors such as F, the blue fluorescence added with the color will lead to extreme blur or haze in the stone.

5. Very Strong Fluorescence

What are Very Strong Fluorescent Diamonds?

With a fluorescence grade above Strong F diamonds, Very Strong Fluorescence of Diamonds refer to the extreme glow of blue with an overshade of white on it. Here, the saturation of fluorescence is too high under UV light. According to GIA, a low percentage of one in ten diamonds exhibit V. Strong Fluorescence. In case of very strongly fluorescent diamonds, clarity of the rock can go down up to 20%.

Pros and Cons of Fluorescence of Diamonds

Pros of Fluorescence of Diamonds

· Make it Look Whiter

When colored diamonds are mixed with fluorescence, they tend to become clear. This is particularly true with yellow diamonds that turn white when seen with blue fluorescence.

· Special Blue-White Diamonds or Jager

Once famous as a variety of diamonds called Jager or Blue-White Diamonds, these are called premium diamonds although they have very strong fluorescence.

· Bring Down the Costs

With strong and very strongly fluorescence diamonds bringing down up to 20% of the diamond value, there is a much to save with fluorescence of diamonds in engagement rings.

Cons of Fluorescence of Diamonds

· Hazy/ Oily Clarity

When fluorescence is too strong of a diamond, it leads to haziness in case of strongly colored diamonds. The same leads to decrease in clarity too.

· Additional Flaws

Most overly fluorescent diamonds also come with many other negative traits and if you’re buying fluorescent diamonds, ensure you buy from a credible jeweler or vendor.
